  • Composition for polyurethane foam, preparation for polyurethane foam, polymer polyol preparation for polyurethane foam, production processes therefor, and polyurethane foam
    Patent number: 10494469
    Abstract: This invention relates to a preparation for a polyurethane foam and a polymer polyol preparation for a polyurethane foam, each of which exhibits high coloration and discoloration inhibition properties over a long period of time when stored, and to a composition for a polyurethane foam, which is excellent in storage stability and is preferable as a resin premix. The composition comprises (i) at least one polyol, (ii) a compound having a P?N bond, (iii) an antioxidant having a hydroxyphenyl group, (iv) at least an acid and/or its salt, (v) a catalyst for polyurethane foam production and (vi) a blowing agent.

  • Polyol, polyol composition, and flexible polyurethane foam using the same
    Patent number: 9382372
    Abstract: Disclosed are a polyol with a molecular weight distribution Mw/Mn of 4 or more, obtained by reacting a compound comprising an alkylene oxide compound (II) having a hydroxyl group in a base polyol (I) with a molecular weight of 2000 or more; and a polyol composition for a flexible polyurethane foam, comprising a polyol compound and a crosslinker, wherein the crosslinker comprises a polyol (a) with a hydroxyl value of 50 to 1100 mgKOH/g and with a primary hydroxylate ratio of 25% or more and 60% or less, which is obtained by an addition of a compound comprising alkylene oxide compound (ii) having a hydroxyl group to active hydrogen compound (i).
